Python 2.7 is obsolete and no longer supported (as of 1 January 2020). You should consider using the latest version (currently Python 3.8.5). For more information, see this.
The modules you are looking for are core modules of standard Python distribution, therefore they are installed when installing Python itself.
They are installed with your python as part of the standard library, if they are missing, something is wrong with your Python installation and you should reinstall it
